ABSTRACT:
A combined hydraulic circuit to be used with a hydraulically powered implement of a motorized equipment and its engine-driven host vehicle. The combined hydraulic circuit allows the implement to be operated with a vehicle, such as a tractor, which does not have the adequate capacity to power the implement without the usual requirement of using an hydraulic fluid reservoir and a filter in the independent hydraulic circuit of the implement. Instead, the implement uses the tractor hydraulic circuit to clean, cool and pressurize in part the hydraulic fluid in its hydraulic circuit which has a hydraulic motor or a hydraulic cylinder driven by a hydraulic pump. This hydraulic pump can be a generated orbital rotor pump since the supplied fluid entering the pump is already pressurized unlike a circuit that uses a hydraulic fluid reservoir. The implements may be rotary brooms, mowers, portable saw mills, hoeing machines, loaders or snowblowers.
